Abstract

A sealing cap for a container for holding a medical liquid comprises a cap body and a connection device having a sealing element arranged on the cap body. The sealing element is arranged at the opening and is retained in the cap body in a clamped manner by a, preferably annular, flanged rim. The connection device has a break-off piece, which is firmly connected to the cap body and covers an outer face of the sealing element in the outward direction. The break-off piece is integral with the cap body, is connected to the cap body by a predetermined breaking point where the break-off piece can be detached from the cap body. The sealing element outer face is substantially flat and is accessible for wiping to provide a sealing cap having a sealing element arranged that can be simply and reliably disinfected.

First claim

The invention claimed is:

1. A sealing element for a connection device of a container for holding a medical liquid, comprising a sealing head, on an outer side of the sealing element, a sealing body adjoining the sealing head, and a ring collar connected to the sealing body via a flange, wherein the outer side of the sealing element is substantially flat and disposed above a top side of the ring collar, wherein a puncture site in the sealing head is at least partially slotted with a cross slot, and/or a marking that is at least partially circumferential and arranged around the puncture site wherein on the top side of the ring collar and/or on a bottom side of the ring collar, a plurality of spacers are arranged distributed over the periphery.

2. The sealing element of claim 1 , wherein a bottom side of the ring collar is situated lower than a bottom side of the sealing body and the ring collar thus extends beyond the bottom side of the sealing body.

3. The sealing element of claim 2 , wherein the bottom side of the first sealing element is substantially flat.

4. The sealing element of claim 1 , wherein the sealing element is shaped to be pierced by a spike of a conveying device.

5. The sealing element of claim 1 , wherein the sealing element reseals automatically when a conveying device is removed from the sealing element.

6. The sealing element of claim 1 , wherein the marking extends as a broken circle around the puncture site.

7. The sealing element of claim 1 , wherein the marking comprises an at least partially circumferential burr.

8. The sealing element of claim 1 , wherein the cross slot extends from an outer side of the sealing element into the sealing body of the sealing element to a depth of 0.5 mm to 2 mm.

9. The sealing element of claim 1 , wherein the sealing element has at least one spacer.

10. The sealing element of claim 1 , wherein the plurality of spacers comprise elevations or webs that extend radially outward form a central axis of rotation of the sealing element or the plurality of spaces comprise raised bosses distributed on a bottom side of the sealing element.

11. The sealing element of claim 1 , wherein the sealing element possesses a central thickness of 2 mm to 6 mm, and/or a total diameter of 4 mm to 14 mm.

12. The sealing element of claim 1 , wherein the sealing element possesses a central thickness of 3 mm to 4 mm, and/or a total diameter of 10 mm to 12 mm.

13. The sealing element of claim 1 , wherein the sealing head possesses a diameter of 2 mm to 10 mm and/or the first sealing element possesses a total diameter of 8 mm to 14 mm.

14. The sealing element of claim 1 , wherein the sealing head possesses a diameter of 5 mm to 8 mm and/or the sealing element possesses a total diameter of 10 mm to 12 mm.

15. The sealing element of claim 1 , wherein the outer side of the sealing element is substantially flat in a same plane as an upper rim of an opening of a cap body and lies disposed above a top side of the ring collar.

16. The sealing element of claim 1 , wherein the sealing element is dimensioned and configured to contact and fit over an opening of a sealing cap for attachment to a container for holding a medical liquid.

17. The sealing element of claim 16 , wherein the ring collar is disposed in an associated recess of the sealing cap and clampingly held there, so that, by contact of the ring collar, the sealing element is connected to the sealing cap.

18. The sealing element claim 1 , wherein the sealing element is made of an elastic material, softer than a material comprising a cap body, and further comprising a polyisoprene or a thermoplastic elastomer puncture site.

19. The sealing element claim 1 , wherein the sealing element is slotted at least in some sections or throughout for connection of one or more of a conveying device, an injection cannula, or preferably a pin, at the outer side of the sealing element to pierce the sealing element, such that when the sealing element is pushed aside, wherein the ring collar remains on a holding device of a sealing cap and the sealing element is held in position on the sealing cap, such that when the conveying device is removed from the sealing cap, then the sealing element automatically closes as a resealable element, so that the opening of the sealing cap is in turn sealed against passage of liquid out of the container.

20. A sealing element for a connection device of a container for holding a medical liquid, comprising a sealing head, on an outer side of the sealing element, a sealing body adjoining the sealing head, and a ring collar connected to the sealing body via a flange, wherein the outer side of the sealing element is substantially flat and disposed above a top side of the ring collar, wherein on the top side of the ring collar and/or on a bottom side of the ring collar, a plurality of spacers are arranged distributed over the periphery.
